title: Morphologic hysteroscopic criteria suggestive of endometrial hyperplasia.
abstract: OBJECTIVE
  To evaluate the morphologic hysteroscopic criteria leading to a diagnosis of endometrial hyperplasia and compare their accuracy with that of histology.
  
  
  METHODS
  A total of 95 hysteroscopic examinations were evaluated. Of these, 37 had a histologic diagnosis of normal endometrium and the remaining 58 of simple or complex endometrial hyperplasia. We compared the morphologic hysteroscopic criteria for the two groups using Pearson's chi-squared and Fisher's exact test.
  
  
  RESULTS
  Only the presence of endometrial glands presenting a cystic pattern at hysteroscopy gave statistically significant results (P < 0.05), with low sensitivity (15.79%), high specificity (97.29%) and a relative risk of 6.75. With a prevalence of endometrial hyperplasia of 22.97% in a population of women with metrorrhagia, the positive predictive value was 63.53% and the negative predictive value was 79.40%.
  
  
  CONCLUSIONS
  Additional, prospective studies are needed to determine the real value of the diagnostic morphologic parameters under consideration.
